Driver:MIPS
MIPS
This article and the corresponding MAME driver focus on computers sold by MIPS Computer Systems which use MIPS R2000/R3000 processors and run RISC/os (also known as UMIPS), a port of UNIX System V release 3 with BSD extensions.

Preparation
Prerequisites
TODO: mame version, riscos files, tap adapter
Network
TODO: set up the bfs and rsh networking tools and environment.
Storage
Use chdman createhd to prepare a new CHD for the operating system installation, and then chdman addmeta to apply a manufacturer string used to identify the drive make/model information that will be returned by the SCSI INQUIRY command. The geometry used below matches one of the entries in the RISC/os 4.51 /etc/disktab.
chdman createhd -o rs2030.chd -chs 1689,15,80 chdman addmeta -i rs2030.chd -t IDNT -vt "CDC 94601 1.00"
The SCSI INQUIRY response data (defined by the IDNT meta-data tag in the CHD) should consist of an 8 character manufacturer name, 16 character model number, and 4 character version number, all left justified and padded with spaces.
Configuration
TODO: mame configuration
Installing RISC/os
Environment
After powering on the system, you should be presented with a firmware monitor prompt. The help command shows the syntax recognized, and additional information may be found in the manual[2].
To complete a network installation, it's important to set the system TCP/IP address to one that matches the external networking environment, using the setenv command. The current environment settings are retained in non-volatile memory, and may be displayed using printenv.
setenv netaddr 192.168.137.2
Format
The format utility allows disks to be partitioned, labelled and formatted. There are two versions of this utility, with format.std being used for all but the Rx2030 system, which has its own dedicated version format.2030.
Launch the applicable format utility using the boot command, being sure to provide the path name matching your BFS or TFTP data path.
boot -f bfs()tree/stand/format.2030
Once format is launched, answer the prompts as follows.
| Prompt | Response |
|---|---|
| name of device | dksd |
| controller number | 0 |
| unit number | 0 |
| device parameters | 0 |
| fast file system | y |
| dump device parameters | n |
| modify device parameters | n |
| dump partition table | n |
| modify partition table | n |
| read factory defects | n |
| perform format | n |
| perform scan | n |
| media defect command | q |
| perform mapping | n |
| dump bad sector table | n |
| write new volume header | y |
Miniroot Installation
Launch the stand-alone shell sash and use it to copy the miniroot filesystem from TFTP to the root partition of the hard disk.
boot -f bfs()sash.2030.fix cp bfs()root.fs dksd(0,0,1)
This process should take a little over 10 minutes to complete, after which RISC/os may be booted using a kernel from TFTP.
boot -f bfs()unix.i2000_std root=sdc0d0s1
From the miniroot shell prompt, configure the environment to specify a network installation, and start the RISC/os installation utility.
